Electroplating
from class: Intro to Chemistry Definition Electroplating is a process that uses electrical current to deposit a thin layer of metal onto the surface of another material. It is commonly used for improving corrosion resistance, enhancing appearance, and reducing friction.
congrats on reading the definition of electroplating . now let's actually learn it.
Predict what's on your test 5 Must Know Facts For Your Next Test Electroplating involves an electrolyte solution containing metal ions that are reduced and deposited on the cathode. The object to be plated serves as the cathode, and a bar of the plating metal serves as the anode. Reduction reactions occur at the cathode, while oxidation reactions occur at the anode during electroplating. Faraday's laws of electrolysis can be used to calculate the amount of substance deposited during electroplating. Common metals used in electroplating include gold, silver, nickel, copper, and chromium. Review Questions What is the role of the electrolyte solution in electroplating? How does Faraday's law apply to calculating the amount of metal deposited during electroplating? What types of metals are typically used in electroplating and why? "Electroplating" also found in:
